In the tough world of High pressure, High temperature valve applications, Pressure seal gate Valve continue to provide a wide range of industries with a safe, leak free, pressure containing boundary.
Pressure seal Valves are available in many material qualities such as A105 forged and Gr.WCB cast, alloy F22 forged and Gr.WC9 cast; F11 forged and Gr.WC6 cast, austenitic stainless F316 forged and Gr.CF8M cast; for over 500°C, F316H forged and suitable austenitic cast grades.
Studs/nuts/bolts are tightened to prescribed torques in a pattern defined by the manufacturer to affect optimal sealing. However, as system pressure increases, the potential for leakage through the body/Bonnet joint also increases.
{keyword}.Many valves can adapt to a variety of working conditions, but if the valve material is unreasonably selected, the performance and service life of the valve will be greatly reduced.
